Question

我有一个看起来像

的Sql Server 2008 R2连接字符串

  <add name="DBConnectionString"
providerName="System.Data.SqlClient"
connectionString="Data Source=AYZ;Initial Catalog=AYZ;User ID=AYZ;Password=AYZ;"/>

尝试使用EnterpriseLibrary.Data创建新的SQLDatabase实例时出现上述错误。

connString =ConnectionStrings.ConnectionStrings["ConnectionString"];
Database objDB = new SqlDatabase(connString);

详细例外情况如下：

System.FormatException was unhandled by user code
  Message=Invalid character in a Base-64 string.
  Source=mscorlib
  StackTrace:

       at System.Web.HttpApplication.RaiseOnError()
  InnerException:

请帮我解决一下。

感谢。

Answer 1

您在连接字符串属性的末尾缺少"。它应该是：

<add name="ConnectionStringName"
    providerName="System.Data.SqlClient"
    connectionString="Data Source=ServerName\InstanceName;Initial Catalog=DatabaseName;"/>

Answer 2

连接字符串必须加密才能工作。负责该项目的团队使用base64encode.org对字符串进行编码。

Base-64字符串中的无效字符“使用ASP.NET
